How to keep them: Link
- Generally speaking the tank should be at least 6 times bigger than the space the cockroaches occupy.
- You need to provide your cockroaches with a good substrate and with hiding places.
- Cockroaches generally eat fruit, vegetables, moistened dry cat food, moistened fish food, rotting wood and rotting leaves.
- Not all species eat the same.
- Some species only live of specific food sources such as rotting woods, while others can live off anything.

(Blattella germanica) is interesting that in our country this Russian dubbed cockroaches, but its Latin name would rather suggested that it is the German cockroach. If it is a protectorate name change I do not know. Russian is everywhere, where it is warm. In bakeries, laboratories, hotels hospitals. These cockroaches have occurred eg. Even (ex) spouses Ilona David in the reality show Wife Swap. Wherever there is a man leads him unequal struggle. Initially it seemed that the insecticides used to kill Russians looks good, but later turned out to be more and more often individuals who are immune to the effects of the poison. Finally, they had to start using other substances. The eggs hatch larvae Russians after two to three měsích and lasts ten months before the larva changes into an adult. This insect is very annoying especially by fouling their droppings practically everything that was not enough to invalidate nakousáním.

The German cockroach (Blattella germanica) is a small species of cockroach, typically about 1.1 to 1.6 cm (0.43 to 0.63 in)long. In colour it varies from tan to almost black, and it has two dark, roughly parallel, streaks on the pronotum running anteroposteriorly from behind the head to the base of the wings. Although Blattella germanica has wings, it can barely fly, although it may glide when disturbed. Of the few species of cockroach that are domestic pests, it probably is the most widely troublesome example. It is very closely related to the Asian cockroach, and to the casual observer the two appear nearly identical and may be mistaken for each other. However, the Asian cockroach is attracted to light and can fly rather like a moth, while the German cockroach cannot.
